Question

What is the space in which grass should be planted in a land which has a perimeter of 60 feet?

• A. 200 square feet
• B. 250 square feet
• C. 300 square feet
• D. 400 square feet

Answer 1

The correct option is A 200 square feet

Perimeter of the land = 2 (20 + Width)

60 = $2\times 20$ + 2 × Width
60 = 40 + 2 × Width
20 = 2 × Width
Width = $20÷2$ = 10
Width = 10 feet

Area = Length × Width
= $20\times 10$
= 200 square feet

Space in which grass should be planted = 200 square feet
